Biodiversity

What is Biodiversity?

Biodiversity is the variety of life, be that plants, animals, fungi or micro-organisms, as well as the communities they form and the habitats in which they live. It is essential for people, providing vital services like clean water, carbon storage, underpinning our health and wellbeing and for the intrinsic value of iconic species like salmon or kingfisher.

Ecosystems with high biodiversity can more efficiently recycle water, oxygen and carbon and contain a thriving community of species. Enhancing biodiversity, for example by creating farmland buffer strips along watercourses, can protect our raw water resources and boost resilience to flooding.

What is Yorkshire Water doing for Biodiversity?

Under a developing corporate Biodiversity Strategy, Yorkshire Water holds the following four long term aspirations for biodiversity:

  1. To achieve a net gain to biodiversity through our operations.
  2. To improve the ecological resilience of our rivers and catchments.
  3. To give a strong voice to nature in our decision making.
  4. To help customers engage with their river and surrounding natural ecosystems.

Our work is delivered in close collaboration with our Biodiversity Advisory Group. The Biodiversity Advisory Group, is a group of external stakeholders who support our understanding of biodiversity issues and the development of informed and balanced policy making and investment.  They offer advice, guidance and constructive criticism to us, to help ensure that we are implementing our statutory obligations in a way that aligns with regional plans restoring and enhancing biodiversity. The group comprises of representatives from Rivers Trusts, Wildlife Trusts and CaBA Partnerships across our operational area.

Below we summarise some of the ways in which we are delivering against these aspirations.

Funding to External Partners

Key highlights of Yorkshire Water's Biodiversity Enhancement Programme

Yorkshire Water frequently partners with other organisations and provides funding where there are positive outcomes for biodiversity. This is through closely working with third parties, either directly, or through our external Biodiversity Enhancement Programme, where we work with others to undertake projects which can help to achieve one of the following aspirations:

  • To achieve a positive benefit to priority habitats and/or species in Yorkshire Water's operational area.
  • To help improve the ecological resilience of rivers and catchments in Yorkshire.
  • To help Yorkshire Water customers to engage with their river.

An independent impact evaluation report has been compiled to summarise achievements of the Biodiversity Enhancement Programme which can be accessed by  clicking here .

Below are examples of projects that we have funded with third parties with links for further information:

Wild Trout Trust - Tackling Resilience On Underperforming Tributaries (TROUT) programme

The project focusses on improving spawning and nursery habitat for brown trout, a priority species under the UK post-2010 Biodiversity Framework, but the wider ecological improvements associated with each project component such as restoration of the riparian fringe will benefit multiple priority species such as reed bunting, common lizard, common toad, otter, water vole and hare.

By restoring habitats and tackling forcing factors on 9 tributaries across Yorkshire, the project will not only make those systems more ecologically resilient, but will also reduce the effect of those forcing factors on physical habitats and their associated flora and fauna via longitudinal connectivity in the larger channels downstream. Tributary networks are used both by resident and ‘migratory’ trout moving in during spawning from the main river channel. Thus, tributaries have a disproportionately high importance for critical components of the trout life-cycle and hence the population across a catchment.

Yorkshire Water were one of a number of funders to the Beacon Lagoons Little Tern Project. Beacon Lagoons is the only colony of little terns in Yorkshire. Funding went towards fencing, preparing the site for them such as clearing litter, installing platforms and monitoring the population through nest monitoring and ringing individual birds.

Aire Rivers Trust

Yorkshire Water has funded the removal of two barriers to fish passage on Loadpit Beck, unlocking an additional 600m of habitat connectivity. Additionally funding will allow the removal of Himalayan Balsam along a continuous section of beck.

Rodley Nature Reserve

Yorkshire Water provided funding and technical assistance to redevelop the duck marsh at Rodley Nature Reserve. The work is to improve habitat diversity for wetland species in the hope new species such as little ringed plover, common tern among other passage birds will be attracted to the area.

Catchment Based Approach - The Aire, Don and Calder Catchment Partnerships

Through Yorkshire Water’s commitment to working with Catchment Partnerships under the CaBA principles, we have provided core funding to the host organisations of the Calder, Don, and Aire Catchment Partnerships to employ a full time staff member. This has led not only to on the ground action on biodiversity, but the recruitment of citizen science volunteers and the winning of additional funding through government and private sector investment. To date around £8 has been realised by every £1 of YW investment.

Calder Rivers Trust

Yorkshire Water have funded the Calder Rivers Trust to undertake work across the Calder catchment, including floodplain reconnection, riparian habitat restoration and river channel re-naturalisation including weir bypass. Baseline surveys including habitat, river MoRPh, otter, water vole and CHEGD grassland fungi were undertaken prior to the works. The project will run from 2022 to 2027.

Don Catchment Rivers Trust

Yorkshire Water provided funding to the Don Catchment Rivers Trust in 2022. The funding has been primarily used to fund events, advisory visits, soil health monitoring, biodiversity surveys and project management as part of the Dearne Valley Farmer Cluster.

The farm cluster will run a launch event and training workshops, provide tailored one-to-one farm advice visits, undertake baseline monitoring in two key areas (soil and farmland breeding birds) so that farmers can understand the current condition of their land and track improvements.

Funding also went towards installing measures on the River Hipper to increase flows and benefit the white-clawed crayfish population present.

Yorkshire Wildlife Trust

Yorkshire Water provided the Yorkshire Wildlife Trust funding to enhance sites across the Dearne Valley included Lundwood, Darton and Wombwell. The aim of the project was to maximise the value of the area across the Dearne Valley Network.

Works included the creation of ponds and woodland, enhancement to wet woodland for example clearing dense willow scrub, installing willow tit nesting boxes and posts and species and habitat surveys.

The works contributed in helping safeguard the willow tit as part of the back from the brink project. For more information please click  here .

Riverlution by the River Stewardship Company, Friends of the Dearne and Denby Dale Parish Council

Yorkshire Water provided funding to the Rewilding the Dearne project. A section of fencing has been installed along the River Dearne to stop cattle poaching. 12 heather bales were installed into the tributary channel of the Dearne at Clayton West to create 4 semi-permeable dams to slow the flow during spate and divert run-off into riparian buffer strips and reduce nutrient run off. An area of wetland has also been installed as well as large woody debris installed to restore the river channel and tree planting.

River Holme Connections - River Resilience, Holme Catchment

River Holme Connections is passionate about making the Holme catchment a better place for people and wildlife. With the help of dedicated volunteers, they work to improve biodiversity, tackle invasive non-native species, clean up green spaces, educate people about the importance of river ecosystems and improve recreational opportunities for the whole community. Yorkshire Water are supporting River Holme Connections with invasive species management, as well as providing funding to employ a river ranger and a number of year in industry students to help deliver improvements across the Holme catchment.

Sheffield and Rotherham Wildlife Trust

The financial support from Yorkshire Water allowed the "Otterly Amazing!" project to go ahead as the final piece of the funding puzzle along with Wren Biodiversity Action Fund, Garfield Weston Foundation, Banister Charitable Trust and members of the public who donated to the ‘otters fundraising appeal’.

A total of 6.9 ha of river habitat improvements were achieved including creation of ponds, river, reedbed, wet woodland and floodplain restoration, the re-naturalisation of 0.44 km of river through the construction of a series of in-channel berms, training volunteers, conducting otter surveys and hosted a public event.

Sheffield and Rotherham Wildlife Trust

Yorkshire Water provided funding to the Sheffield and Rotherham Wildlife Trust to improve the quality of wildlife habitats at three sites on Rotherham's rivers, the Don and the Rother.

The funding installed post and wire fencing to retain the site as stock-proof enabling the ongoing conservation works to continue as well as gates to allow vehicle access around the sites.

Sheffield and Rotherham Wildlife Trust - Rotherham Rivers

Sheffield and Rotherham Wildlife Trust are delivering a strategically planned programme of habitat improvements on the River Rother and its tributaries between 2021 and 2027, with funding provided by the Environment Agency, Highways England and Yorkshire Water. Works include fish passage, floodplain reconnection and invasive species control.

Don Catchment Rivers Trust

Yorkshire Water provided funding to the Don Catchment Rivers Trust to improve the ecological condition of Moss Brook by enhancing habitat quality and connectivity. This was achieved by:

1) Tackling an obstacle to fish passage

2) Improving instream and riparian habitat

3) Removing encroaching scrub from a riparian fen also part of the Moss Valley SSSI

Lea Brook Valley CIO

Lea Brook Valley is the name given to the green corridor surrounding Lea Brook within the developed area of the town of Dronfield, stretching for around a mile.

Yorkshire Water provided funding for the planning, construction, training and material costs to enhance the biodiversity of the existing wetland habitat of a storm water retention pond which had become silted up and overgrown. The project occurred over 2 years and included training volunteers to be able to manage the site in the future.

Works included the excavation of deeper ponds, removing silt, deepening/widening inflow channel, lining the base of the ponds, removal of reedmace, clearing scrubs, managing hedgerow, cutting and removing aisings from a grassy bank, planting suitable perennials around the pond, building log piles and erecting viewing platforms.


Habitats on our Land

Between 2021 and the end of 2024 we have undertaken surveys of our land holdings which equates to around 27,000ha. The surveys have been completed on around 24,000ha which is just below 90% of the total area. The work we have carried out encompasses recording of the habitats present in line with the UK Habitat Classification methodology and a condition assessment from the 3.1 DEFRA metric. These surveys will also allow us to recognise opportunities where enhancement or conservation can occur. As well as the data being shared directly with local authorities, ecological record centres and NGO groups. Below is the data that has been collected and managed up to March 2025. To view it as a web map please click  here . Please note the following:

  • All the data has been completed using the condition assessments from Metric 3.1 and these will not be updated for the time being due to the differences between the statutory metric and 3.1.
  • The data has been collected using the UK Habitats Classification methodology Version 1, please note that changes between Version 1 and Version 2 may affect the habitat type.
  • The minimum mapping units used for the surveys are as follows:
    • Large scale – upland areas, 2500m2 or 50m linear.
    • Medium scale – woodlands and hedgerows, 400m2, 20m length.
    • Small scale – everything else e.g. grassland, 25m2 and 5m length.
  • Not every metre of every land parcel has been surveyed.
  • While every effort to record dry stone walls and fences has been made in some areas these will not be displayed due to high number and time associated with it.
  • Data management is an ongoing process therefore not all survey data collected is displayed.
  • Only areas under Yorkshire Water ownership are displayed.
  • Please note while Yorkshire Water owns the land they may not be responsible for its management due to tenancies or third party rights.
  • Some areas have been mapped from adjacent land or through desk study.
  • Due to the additional training required and separate module of the metric condition assessments have not been undertaken for any watercourses including ditches.
  • For any information regarding the data please contact biodiversity@yorkshirewater.co.uk

Yorkshire Water Baseline March 25

We also commission works to understand important protected species populations and their locations on our land. For example we have commissioned detailed reptile population surveys of land in the upper Nidd valley aiming to improve knowledge of the adder population in particular. The surveys have been undertaken between Summer 2022 and Spring 2023 and involved repeated walked transects at two of our reservoirs to visually record adders and other reptiles and monitoring at hibernation sites. Information on sightings from Nidderdale AONB, landowners and members of the public is also being collated and - along with the detailed survey information - will help us to establish the abundance and distribution of adders in the area, and plan future land management to benefit this declining reptile species.


Conservation and Enhancements

From understanding what we have present on our land allows us to understand opportunities for enhancement and conservation. Below are some examples of the work we have been undertaking.

Working with the Environment Agency and the North Yorkshire Crayfish Forum, Yorkshire Water are committed to the conservation of white-clawed crayfish and are currently finding suitable locations for ark sites in our assets where they will not affect day to day operations and will preserve populations.

At our Tophill Low Nature Reserve we have created a greater water parsnip plant nursery for this Nationally scarce species to enable translocations of the plant.

We have a number of Local Wildlife Sites on our land. Following the Lawton principles, we have been focussing on making good sites better or bigger. We have been investigating which sites would benefit most from a change in management practices and have shortlisted a number of sites with management plans being written to be implemented from 2023. These include but are not limited to Boltby, Black Moor Common, Beaver Dyke, Dunswell, Moor Monkton, Tadcaster Brickyard and Tophill Low.

Yorkshire Water are working with South Yorkshire Bat Group (SYBG) to support research and bat conservation in the Upper Don catchment. Yorkshire Water have provided funding for monitoring equipment for the group, and we have also installed new bat roosting habitat in woodlands under our ownership. The project aims to study bat activity and species’ diversity at a farm, where a major woodland creation project is linking up existing habitat at two of our reservoirs. This is providing a unique opportunity to study the long-term effect of landscape connectivity improvements on bat populations, whilst engaging with a local community group and promoting better understanding of bats.

Yorkshire Water are exploring other sites for collaborative projects with South Yorkshire Bat Group, including further woodland bat box schemes at Midhope and Langsett Reservoir. Plans to enhance a derelict reservoir building in the Rivelin Valley as a bat roost will also involve the group through consultation in the design and future monitoring of its success. These proposals tie-in with the planned ‘Landscape Laboratory’ project involving Yorkshire Water, Sheffield Hallam University and other stakeholders, which aims to develop the upper Little Don area as a regional hub for landscape-scale ecology and climate research.


Invasive Non-Native Species (INNS) & Biosecurity

Yorkshire Water recognises the importance of biosecurity and as part of our commitments in AMP7 we will be providing training to staff to ensure that biosecurity is incorporated into our every day work.

Invasive non-native species (INNS) not only threaten our native wildlife through out-competing them for food and resources but to ensure that they are not spread or through damage to our assets costs us millions of pounds per year.

Yorkshire Water has been part of the steering group for the development of INNS Mapper as well as contributing funding. INNS mapper allows you to record where you have seen any as well as checking if any INNS are in a specific area as well as recording if any management is currently taking place for eradication or management. If you see any INNS please record them by  clicking here .

Yorkshire Water works in collaboration with the University of Leeds including having placements students and providing unique opportunities for PhD students. We are currently involved with PhD work to understand INNS related sediment load in the Derwent catchment from Himalayan balsam and American signal crayfish. Furthermore, we are involved in PhD work to understand and mitigate the risk of INNS spread via raw water transfer operations.

Invasive zebra mussels encrusting operational pipework

We are also keen to advance our understanding of INNS and have been investigating the use of eDNA surveys for detecting INNS in waterways. The investigation has focussed on developing and/or integrating DNA based methods as a monitoring technique, focused on aquatic INNS on Yorkshire Water assets. We are working with the University of Hull to refine eDNA monitoring techniques for zebra mussels through a PhD. We have also contributed funding to the continued research and development of novel control methods for high risk INNS  such as our collaboration with CABI on biocontrols of Australian swamp stonecrop and floating pennywort.

At Gouthwaite Reservoir (which is designated as a Site of Special Scientific Interest) a management plan for priority INNS will be developed. The management plan will take into consideration the designations placed on the site which is for the diversity of bird assemblage.


Fish Passage

Rodley Fish Pass

Yorkshire Water are committed to improving our rivers to improve the connectivity for biodiversity. Through working in Partnership with the Environment Agency, various Rivers Trusts and other charities we have undertaken a number of river restoration and fish passage projects which includes the removal of weirs or the installation of fish passes. Take a look at our River Health website and how fish passes are a part of this by clicking  here .

Partnership working allows bigger and better results than one company can achieve. We have recently helped salmon to return to the River Don for the first time in 200 years (for more information please  click here ,  here  or for video please  click here  or  here ). We have also funded the  DNAire project  which looks at improvements to the whole Aire catchment and not just those areas under our ownership.

We have completed 17 fish passage projects to date (since 2013) with over £15 million spent so far. The first fish pass to be installed was at the Yorkshire Water owned  Rodley Nature Reserve in Leeds . With over 4000 barriers identified in Yorkshire using the  Rivers Trust website  there is still plenty of work to be done. We are continuing to expand our fish passage programme to realise the benefits of past and ongoing Yorkshire Water investment in improving river water quality.

Below are two examples of the before and after images of barrier removal and a map with the locations of some of our fish passage works with what has been done.

Good News Stories

A 28-hectare site on the moorlands of Harden, Barnsley has been granted Local Wildlife Site (LWS) status following its discovery as an important habitat for protected bat species.

The results of a year-long study have shown the importance of the mines at Harden for four species of swarming bat. The research also found that some of the same species return in winter to hibernate in the sheltered pits. Another four kinds of bat were recorded foraging over the moorlands in summertime, taking the total recorded to eight species for the site. These findings have convinced the Barnsley LWS panel that it is an area worth protecting for the future.

Four nature recovery projects will begin over the summer in Dearne Valley in South Yorkshire, to complement a wider programme of investment at Yorkshire Water’s wastewater treatment sites to improve water quality in the river Dearne.

In partnership with the Yorkshire Wildlife Trust, Yorkshire Water will invest in a range of habitats adjacent to wastewater treatment works in the area. Efforts will improve ponds for amphibians, dragonflies and wading birds and include the planting of trees to help woodland wildlife.

This includes the endangered Willow Tit, the UK’s most threatened resident bird. Since 1970, numbers have decreased by 94%, and they are now extinct in most of their former haunts in the south and south-east of England. For more information please click  here .

Five new fish pass projects on the Rivers Don, Rother and Ryburn are in development to help fish migration in the Yorkshire region thanks to new innovative partnership known as Great Yorkshire Rivers (GYR).

This year, three passes will be added to the river Don, including:

  • Niagara weir, Sheffield;
  • Cheesebottom weir, Thurgoland; and
  • Stocksbridge, near Sheffield.

Meadowgate fish pass (Rother Valley Country Park) is also under construction on the River Rother and Watson Mill fish pass in Sowerby Bridge has been completed on the River Ryburn. For more information please click  here .

Floating pennywort weevils have been introduced as a biocontrol to two sites in West Yorkshire to control the growth of floating pennywort – an invasive non-native species (INNS) which can choke the life out of watercourses. For more information please  click here.
